8. Status indicator
The status of the device is shown by a single LED, located inside the box:
•
If the LED blinks for a period of 1 second, the sensor works properly;
•
If the LED blinks for a period of 3 seconds, there isn‘t communication with the controller;
•
If LED doesn‘t blink, there isn‘t a power supply.
9. Factory default settings
Disconnect the sensor from the bus (switch off the power supply).
Press and hold the “config” button. Don’t release the button, connecting the sensor to the bus
(switch on the power supply).
The “status” LED will be ON for 3 seconds and after this will flash for 7 seconds. After the 10-th
second the LED will be ON.
Release the button. The sensor will restart with factory default settings.
10. Firmware update
The firmware of the sensor can be updated with a Teracom controller which supports
MODBUS RTU or MBRTU-Config software. For more details ask your dealer.
